ACUVUE OASYS vs ACUVUE 2 Acuvue Oasys and Acuvue 2 are well-established contact lens options that have been available for almost over two decades. While both lenses offer extended wear capabilities and are manufactured by Johnson & Johnson Vision Care, Inc., there are notable differences between them. This article aims to provide an extensive comparison of Acuvue 2 and Oasys contact lenses, focusing on various aspects such as design, material, comfort, and pricing.

Design and Prescription Parameters

Acuvue Oasys and Acuvue 2 share some similarities in terms of replacement schedules and wearing details. Both lenses can be worn daily for up to two weeks before needing to be discarded. With approval from your eye doctor, you can also wear them overnight for up to six nights, reducing the replacement schedule to one week. The wide range of prescription parameters and the two different base curves ensure that individuals can find the perfect fit and vision correction tailored to their specific requirements.

Comparison of Material and Parameters

One of the significant distinctions between Acuvue Oasys and Acuvue 2 lies in the lens material. Acuvue Oasys is made of silicone hydrogel (Senofilcon A), while Acuvue 2 is composed of ionic hydrogel (Etafilcon A). As such, Acuvue Oasys, with its silicone hydrogel composition, offers a higher oxygen transmission value, denoted as Dk/t, which measures the amount of oxygen that can pass through the lens to reach the eye. Acuvue Oasys boasts an impressive Dk/t of 147, allowing for increased oxygen flow. In contrast, Acuvue 2 has a Dk/t of 33. The higher Dk/t of Acuvue Oasys implies better oxygen permeability, however readers should be aware that this doesn't necessarily translate into enhanced comfort and an advantage for the Oasys.

Moreover, Acuvue Oasys incorporates HYDRACLEAR® PLUS technology, which supports improved moisture retention and lens surface smoothness. This technology aims to combat dryness and maintain optimal hydration throughout the day. Acuvue 2, on the other hand, features INFINITY EDGE Design, which helps promote comfort by reducing lens interaction with the eyelid.

Additionally, it's worth noting that Acuvue Oasys has a higher modulus (0.7 MPa) compared to Acuvue 2 (0.3 MPa), indicating a slightly firmer, stiffer lens structure. This difference in modulus makes handling the Oasys lenses easier. However, the stiffer nature of Acuvue Oasys may lead to a more noticeable awareness of the lenses or a subtle difference in how they feel on the eyes, in contrast to the softer Acuvue 2 lenses.

Comparing Features

Both Acuvue Oasys and Acuvue 2 offer certain features to address specific needs. Both lenses possess wetting agents, such as PVP (polyvinylpyrrolidone), which contribute to maintaining moisture on the lens surface. They also include a visibility tint, typically blue, to aid in handling and insertion. Furthermore, both lenses are equipped with inside-out marks, denoted as "123," to assist wearers in correctly orienting the lenses during application.

UV protection is another aspect to consider. Acuvue Oasys falls into the FDA Class 1 UV-blocking category and provides 96% UVA and 99% UVB protection. Acuvue 2, classified as Class 2, offers 88% UVA and 99% UVB protection. It is important to note that while both lenses offer UV protection in the tradition of all Acuvue products, they should not be considered a substitute for UV-blocking sunglasses.

Packaging, Pricing, and Offers

Acuvue Oasys comes in boxes with six, twelve, and twenty-four lenses, while Acuvue 2 is typically packaged with six lenses per box. The higher lens count in Acuvue Oasys results in a slightly lower cost per lens compared to Acuvue 2. This price difference of 14 cents per day translates to approximately $51 extra expenses per year for Acuvue 2. It's not surprising that the price discrepancy between bi-weekly or monthly replaceable contact lenses from various online retailers is usually smaller. Keep in mind that pricing may vary based on the quantity of boxes purchased and retailer promotions.
